Background

After launching the Unified Payments Interface (UPI) in April 2016, the National Payments Corporation of India (NPCI) went a step further and announced the UPI based BHIM (Bharat Interface for Money) app to acquire UPI based transactions and route them to all participating banks in India. While the banks have since built their own UPI enabled payments app, they are obligated to accept transactions from non-banking payment apps like BHIM. With the recent changes in the Indian payments landscape triggered by demonetization and the push for digital transactions, the volume of UPI transactions increased ten times over a period of just three months and promises to grow further. Unfortunately, existing UPI infrastructures for most banks are not adequate to cater to this exponential growth.

RS RealEdge™ - The UPI Platform from RS Software

RS RealEdge™ is a proprietary platform from RS Software that enables Banks and Payment Service Providers (PSP) to integrate with the UPI Central Platform. RS RealEdge™ communicates seamlessly with NPCI’s UPI and integrates with Core Banking Systems (CBS). It provides a number of payment APIs that can be consumed by digital banking platforms, enabling mobile and internet based applications for the end consumer.
